As charged particles from the Sun, called the \"solar wind,\" flow outward well beyond the orbits of the planets, they collide with the material between the stars, called the \"interstellar medium\" (ISM). These interactions create energetic neutral atoms (ENAs), particles with no charge that move very quickly. This region emits no light that can be collected by conventional telescopes so, instead, IBEX measures the particles that happen to be traveling inward from the boundary. IBEX contains two detectors designed to collect and measure ENAs, providing data about the mass, location, direction of origin, and energy of these particles. From these data, maps of the boundary are created. IBEX's sole, focused science objective is to discover the nature of the interactions between the solar wind and the interstellar medium at the edge of our Solar System. || ", "hits": 101 }, { "id": 10790, "url": "https://svs.gsfc.nasa.gov/10790/", "result_type": "Produced Video", "release_date": "2011-06-09T12:00:00-04:00", "title": "Voyager Satellites Find Magnetic Bubbles at Edge of Solar System", "description": "The sun's magnetic field spins opposite directions on the north and south poles. These oppositely pointing magnetic fields are separated by a layer of current called the heliospheric current sheet. Due to the tilt of the magnetic axis in relation to the axis of rotation of the Sun, the heliospheric current sheet flaps like a flag in the wind. The flapping current sheet separates regions of oppositely pointing magnetic field, called sectors. As the solar wind speed decreases past the termination shock, the sectors squeeze together, bringing regions of opposite magnetic field closer to each other. The Voyager spacecraft have now found that when the separation of sectors becomes very small, the sectored magnetic field breaks up into a sea of nested \"magnetic bubbles\" in a phenomenon called magnetic reconnection. The region of nested bubbles is carried by the solar wind to the north and south filling out the entire front region of the heliopause and the sector region in the heliosheath.This discovery has prompted a complete revision of what the heliosheath region looks like. The smooth, streamlined look is gone, replaced with a bubbly, frothy outer layer.

Future exploration missions will benefit in design and mission objectives from a better understanding of the changing conditions in this outer region of our solar system.The IBEX has produced a new set of \"all-sky\" maps of our solar system's interaction with the galaxy, allowing researchers to continue viewing and studying the interaction between our galaxy and sun. The new maps reveal changing conditions in the region that separates the nearest reaches of our galaxy, called the local interstellar medium, from our heliosphere — a protective bubble that shields and protects our solar system.In October 2009, scientists announced that the first map data produced by IBEX revealed an unpredicted bright ribbon of energetic neutral atoms emanating toward the sun from the edge of the solar system. This discovery was unexpected to scientists, because the ribbon of bright emissions did not resemble any previous theoretical models of the region.The IBEX spacecraft creates sky maps by measuring and counting particles referred to as energetic neutral atoms that are created in an area of our solar system known as the interstellar boundary region. This imaging technique is required since this region emits no light that can be collected by conventional telescopes. This interstellar boundary is where charged particles from the sun, called the solar wind, flow outward far beyond the orbits of the planets and collide with material between stars. These collisions cause energetic neutral atoms to travel inward toward the sun from interstellar space at velocities ranging from 100,000 mph to more than 2.4 million mph.This second set of all-sky maps, created using data collected during six months of observations, show the evolution of the interstellar boundary region. The maps help delineate the interstellar boundary region, the area at the edge of our solar system that shields it from most of the dangerous galactic cosmic radiation that would otherwise enter from interstellar space. The new findings were published this week in the Journal of Geophysical Research - Space Physics, a publication of the American Geophysical Union. || ", "hits": 32 }, { "id": 10587, "url": "https://svs.gsfc.nasa.gov/10587/", "result_type": "Produced Video", "release_date": "2010-03-12T00:00:00-05:00", "title": "The Cosmic Ray Telescope for the Effects of Radiation", "description": "This animation shows how the Cosmic Ray Telescope for the Effects of Radiation (CRaTER) instrument on LRO works.
